Speed, Velocity, Acceleration

What is speed?

• how far you go
• how much distance is covered over a period of time
• how fast you accelerate
• the change in the location of a object

What is the formula to calculate speed?

• Speed = time/distance
• Speed = distance/time
• Speed = distance x time
• Speed = time x distance

What is velocity?

• the quickness of an object
• the location of an object
• acceleration
• speed in a specific direction

When a car goes around a corner at 20 mph, why do we say it  accelerates?

• The car is accelerating because of the velocity is constant
• The car accelerates because it's going 20 mph
• Cars always accelerate when they are in motion
• The car is accelerating because it's changing direction

Acceleration can be classified as _______________

• Speeding up
• Slowing Down
• Changing directions
• All of the above
